Simulation study on the entrance taxiway operation mode for all day run multi-runway airport

Changing the configuration of the runway and taxiway geometry is an effective measure to improve the airport operation efficiency. Increasing the number of parallel Entrance Taxiways (ET) which is connected to the runway is a general way of saving flights waiting times, but the actual take off length for runway is reduced. To overcome this problem, the new operation mode was applied by increasing the additional inclined ET besides vertical ET which were set at the end of the runway. However, the effect of the additional inclined ET to the airport operation efficiency is hang over. In this study, the physical model of all-day run multi-runway airport was built to study the influence of the additional inclined ET to airport operation efficiency by comparison of runway with vertical ET and with additional inclined ET. It is found that flight delay rate is reduced from 17% to 13.8% for the runway with additional inclined ET. The time of maximum flight delay and the number of delay flights are reduced while the runway is connected to the additional inclined ET. Air delay and taxiing delay are the major reason for the ground delay for arrival flights and departure flights, respectively. Taxiing delay for arrival flights is reduced while the additional inclined ET is operated. Runway capacity has little change by the operation of the additional inclined ET.
